Lost data

Disk manager now shows as blank? Machine had worked fine but I noticed the WD Live TV Hub was not accessible from PC. Checked the box via TV and I can no longer view any files and within in Set Up the Disk Manager screen is empty, and no media is showing in any categories on home screen - any suggestions as to where my files maybe? Help would be very appreciated… thank you.

Latest firmware installed

Tried resetting to factory defaults

Machine was not in use at the time

Try going to setup then system then Media library the click clear media library
